SPECIFICATION forming part of Letters Patent No. 754,958, dated March 15, 1904. Application filed February 18, 1903. Serial No. 143,991. (No model.)

To all whom, it may concern,.-

Beit known that I,WILLTAM THORNBURGH, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Draft-Rigging, of which the followingjs a specification, reference being had therein to the accompanying drawings.

The invention relates to new and useful improvements in draft-rigging; and it consists in the construction of the side plates having a tie intermediate the ends thereof, together with the particular construction of this tie and its cooperation with the springs, followers, and yoke.

The invention further consists in the construction of a cross-block or abutment shouldered against the sides in a tandem draft-rig'- ging, the springs acting against the opposite ends thereof, and,further, in the construction, arrangement, and combination of its various parts, as more fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical central section of my improved draft-rigging. Fig. 2 is a horizontal section therethrough. Fig. 3 is a cross-section on line Fig. 2; and Fig. i is a sectional perspective illustrating the central abutment or cross-block, the tie, and its cooperation with the yoke, side plates, and followers.

A represents the usual draft-timbers in a railway-car, to which the side plates B are secured-as, for instance, by means of the bolts O.

At substantially the middle of the side plates are the vertical flanges I), separated from each other, and preferably having overhanging edges-in other words, being hook shapedto form ways for the flangesE on the central block F. This block F performs several functions, lirst being that of an abutment against which the inner ends of the springs G Gr bear to take up the end thrust thereof when these springs are compressed by the movement of the yoke H in either direction, this yoke being of the usual construction, and I'therefore do not deem it necessary to further describe it.

The block F when it is provided with the flanges E also acts as a central tie between the two side members, and with the construction to be hereinafter described it will be obvious that it also forms a tie between the two parts of the yoke; but for convenience of description I will refer to this block as a tie-block or a cross-block.

I is a bottom plate fitting between the two side plates and secured in position by means of cross-bolts J, this bottom plate lying in the operating parts including the cross-block.

- K represents the outer followers at opposite ends, sliding' between the two side plates and against'which one end of the springs directly abuts, and L represents the two inner followers, bearing against the cross-block and against which the two opposite ends of the springs abut.

The followers K are limited in their endwise movement by the lugs a and and these followers therefore necessarily project into the recesses formed by the fianges or lugs upon its side plates,while the followers L, abutting against the cross-block,may be of much smaller size than usual and may be of a size to fit 4within the space within the hanged side walls of the side plates.

Secured to the top and'bottom members of the yoke are the lugs M and N, these lugs preferably being of a width corresponding to the width of the cross-block and being secured to the yoke in any suitable manneraa for instance, by means of rivets e. M and N preferably have the ends inturned, which inturned ends are provided with the flanges cl, which engage in complementary guides e in the sides of the cross-block. I show in these drawings in addition to the springs G Gr the auxiliary springs O to get greater spring resistance. These may be used or not, according as greater or less spring resistance is required;

The parts being thus arranged and constructed, their operation is as follows: Assuming that the draft-bar is moved to the left, the

These lugsV righthand follower K will compress the spring G against the cross-block, while the lugs on the yoke will move the left-hand follower L endwise and compress the spring Gr against the left-hand follower K. On movement of the yoke to the right or reverse 0f this movement the left-hand spring will be Vcompressed against the cross-block, while the right-hand spring will be compressed against the right-hand follower K.

It will be obvious from the construction shown that I get a solid abutment in the middle of the sides against which the compression of the springs may be exerted and that if this abutment is provided with flanges, such as E, it will act as a tie member between the two side pieces and prevent the possibility of lateral strain being applied to said side plates even if the draft-timbers should tend to warp or bend. It is also evident that the two members of the yoke are tied together by means of the interlocking lugs thereon engaging' in the guide-grooves in the cross or tie-blocks.

The entire spring-rigging, including the cross-block, maybe removed by taking out the bolts J on the bottom plate I.

That I claim as my invention isl. In a draft-rigging, the combination of the side plates, of a tie between these plates intermediate the ends thereof, resilient means upon opposite sides of the tie, and a draft attachment adapted to operate the resilient means simultaneously, said draft attachment having an interlocking engagement with the tie.
